Abstract

The importance of fire safety in public transportation has been increased. Among interior materials vulnerable to fire, cushion materials made of polymer-based foam require high flame retardancy due to toxic gas generation and secondary propagation of flames. Since the silicone foam impregnated with the flame-retardant filler changes its mechanical properties, a mechanical reliability analysis was performed on it. In order to predict the mechanical behavior of hyperfoam, finite element analysis was performed using the Ogden model. In addition, parameters were obtained through an optimization process in consideration of the viscoelastic properties of the specimen, and the transmissibility according to the external vibration frequency were analyzed. As a result, it was observed that the external vibration frequency had a high transmittance of 1 or more between 5 and 15 Hz, while exhibiting a transmittance of 1 or less at frequencies of 5 Hz or less and 20 Hz or more.
